The Tecma Drive slewing bearing line is separate from the slewing drive modules, which have their own guide in the catalogue. A slewing bearing connects two structures that rotate relative to one another; a drive module is a different drive arrangement with its own references. This line includes externally geared, internally geared and ungeared rings. Identifying those differences before comparing size avoids treating a ring and the assembly driving it as the same part.

E.318.22.00.D.1 belongs to the externally geared family; I.650.20.00.C is an internally geared reference, and SD.1055.25.00.B identifies an ungeared ring. Retain all groups separated by full stops: isolated numbers replace neither the full designation nor a dimensioned drawing.
Slewing drive modules, whose designations start with TD and use hyphens, form another catalogue line with its own guide: do not look for them among these references. Nor should the reading of the E., I. or SD. prefixes be transferred to every code containing the letter E; on rings, that prefix only tells the gearing type apart.
The Tecma Drive guide describes cranes, platforms and machinery in which one structure turns relative to another. Identify the stationary structure, the rotating structure and how motion reaches the ring. Where an external pinion drives the assembly, include its location in the overall view.
The fixing geometry matters as much as the visible diameter. Replacing an existing ring requires its hole pattern and seating surfaces to be identified from drawings or installation measurements. A front photograph can show the gearing but does not, by itself, document both mounting faces.
Send the plate or drawing reference, quantity and machine model. Attach photographs of both faces, the gearing where present and the drive connection. Include diameters, height and hole arrangement from the available drawing, stating the units. For a TD module, show the complete plate and installed assembly; defining which components require replacement avoids quoting a ring when the request concerns the module.
The names are not equivalent. The catalogue distinguishes rings and modules; identify the arrangement from its reference.
It is retained here as part of the code without an assigned meaning. Check the arrangement against the unit documentation.
Fixings, height, seating surfaces and drive arrangement must also be identified. A complete drawing supports that comparison.

TECMA DRIVE slewing rings are power transmission components that enable the rotary motion of structures and equipment. They are used in applications requiring controlled and precise rotation, such as cranes, aerial work platforms and orientation systems. MR Accesorios Industriales supplies this line.

TECMA DRIVE slewing rings are large-diameter bearings with internal gearing, designed to withstand combined loads and allow controlled rotation of heavy structures. They are used in applications requiring precise rotary motion and high load capacity, such as cranes, excavators and slewing platforms. MR Accesorios Industriales sells this line.
